Plankton and water was sampled from a site at Cape Bird and the parameters measured include: salinity, light, temperature, biomass of zooplankton and phytoplankton, species identification of zooplankton ...

The effect of UVR on biological systems is wavelength dependent. Action spectrum for DNA damage is an essential component of understanding the effects of increased UVB on a range of Antarctic invertebrate ...

Time course experimental exposure of the Antarctic sea urchin Sterechinus neumayeriembryos to UVR was carried out in a lab to examine the kinetics of UVR induced damage to DNA. Embryos (freshly fertilized ...

Photorepair rates in New Zealand temperate species of echinoderms show a much higher DNA photorepair than the Antarctic species Sterechinus neumayeri. To examine the reason for low rates of DNA photorepair ...

An important aspect of understanding the impact of increased UVR is assessing the ability of Antarctic species to repair DNA damaged through the process of photoreactiviation or photorepair. To repair ...

The long term research program ICECUBE (Coastal Underwater Benthic Ecosystems) provides fundamental information on the structural and functional biodiversity of Antarctic coastal benthic ecosystems. ...

Gastrulation is a critical point in the development of an embryo. Damage to embryos prior to gastrulation via UVR effects on cytokinesis or DNA will have a dramatic negative effect on embryo survival. ...

The spatial spreading of light introduced at a point on the surface of the ice and the temporal spreading of a brief pulse of light injected at a point was measured to clarify the details of the interaction ...

Phymatolithon foecundum is a coralline growth found in the coastal benthic environment. Benthic surveys indicated that P. foecundum is abundant throughout the deep gradients (10-30m depth). A range ...

The biodiversity of the seafloor community at Cape Evans was investigated to determine the structural and functional diversity of the benthic community and resurveyed over several seasons to assess ...

The biodiversity of the seafloor community at Granite Harbour was investigated to determine the structural and functional diversity of the benthic community during the 07-08 season. Scuba based video ...

The transparency of sea ice to UV radiation was measured to determine the effects of enhanced UV levels on Antarctic life. The under ice radiance is controlled by the transmission of the sea ice to ...

UV radiation transmission measurements on sea ice surface and through the annual sea ice into the underlying water column were made during Antarctic spring months (October - November) in conjunction ...

Optical beam-spread profiles were measured on sea ice from McMurdo Sound, with a view to understanding the role of microstructure in the scattering of light in sea ice. These experiments were performed ...

In situ measurements of the the spectral transmission and backscattering of light was conducted on first year ice to characterise the optical properties of sea ice. The average scattering length and ...
